Specification of Letters Patent.

Application filed April 18, 1912. Serial no. 691634.

To all whom it may concern: 7

Be it known that I, GEORGE P. DOHERTY, a citizen of the United States. and a resident of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Copy-Holders, or" which the following is a specification, reference being had to the accompanying drawings. V This invention has relation to certain new and useful improvements in holders employed to give support and hold'copy while being read, and includes a traveling spacing barwhich is successively advanced as the copy is read: and the object of my invention is to provide a device of this general character, of a simple and inexpensive nature and of a compact and durable construction, including a holding means for copy while the traveling spacing bar shall be capable of convenient and accurate adjustment in position upon the copy, in a manner insuring the spacing bar at all times accurately register ing with the lines of the copy, and my invention further includes an adjustable actuating mechanism for successively advancing said spacing bar. 1

\Vith these and other objects inview, the present invention consists in the combination and arrangement or" parts as will be hereinafter 'more fully described and finally pointed out in the appended claims, it being further understood that changes in the specific structure'shown and described may be made within the scope of the claims, without departing from the spirit of the invention.

In the accompanying drawings forming a part of this specification :and in which like numerals of reference indicate similar parts in the several views: Figure 1, shows a front elevational view of a copy holder embodying my invention. Fig. 2, is a side eleva'tional view of Fig.1. Fig. 3, is a top view. Fig. 4, is a rear view. Fig. '5, is a sectional view through the supporting plate and pallet. Fig. 6, shows an enlarged perspective detail of the carriage with parts broken away. Fig. 7 is a central sectional view through the carriage with portions brokenaway.

In my present invention I provide a simrlii eee ee et saq lr see d de i abling typewriter operators, public speakers proof readers, compositors and others to ac curately follow copy; in that I provide an apertured traveling I spacing bar' which'is successively advanced over the copy, so that 1 the consecutive line is always within the aperture or the spacing bar, thereby avoiding repetition or omission of a line in following the copy. I g r In the accompanying drawings the nu meral 1 designates a suitable base'tolwhich is secured the standard 2, which has it's up per end slotted asis shown at'5, in Fig. 4. Extending transversely across the upper slotted end of thestandard 2, is the bolt 3, carrying the wing nut 4, while pivotally held upon the bolt 3, is the ear 6, of the base plate 7, whichby means of the screws 8, is secured to the'pa'llet 9. This pallet is preferablyof sheet' metal andhas'the two similar side flanges a, upper flange a", and the lower flange a". of the pallet and adjacent: to one of the flanges a, as shown in Fig. 4, is the preterably sheet metal supporting plate 10, which is .secured to the pallet by any suitable means. 7 At its upper end asshown' clearly in Fig. 5, the supporting plate 10, has the apertured flange 14, extend- Slid ably held within the apertures 2 and 1', of the members 14 and 11, shown Fig.

5, is the'trip-rod D, which has its upper end threaded as shown at '17. Held upon the threaded end 17,, is the" stop nut 18, and the Secured to the rear lock nut 19. At a suitable point below the I stop nut 18, is located the tensionnut 20, and interposed between this nut 20, and the outstanding flange 14,- is the coil spring 21,

normally forcing the trip-rod D, upward.

At its lower end this trip-rod D, is pivotally secured by meansof the pin 16 shown in Fig. '5, to the spacing lever. 41, which by means of the pin 40, is pivotally connected tothe link 39, carried upon the pin 13. As

shown in Fig. 5, the lever 41, limits the up- V V ward movement pf the tripped B, which are secured within the flang and arm 11. Slidably held upon these two guide bars A and B, is a carriage 23, having the flanges 8 and 9, shown in Fig. 5. By means of these flanges the carriage is accurately guided upon the bars A and B. In front, the carriage is provided withthe collar 2, encompassing thetrip-rod D. In order to tensionally hold the carriage 23, to the barsA and B, I provide a curved spring 33, as shown in Fig. 7, which has its end 34, clamped upon the carriage and held by means of a screw 6'.

At a suitable point as shown in Fig. 6, thecarr age is provided with the screws 6 and b, the first giving pivotal support tothe chisel-edged dog 24, while the remaining pin 7), pivotally suppo-rtsthe chisel edged dog.

releasing lever 28, this lever having the projecting operating end 29. Intermediate of its ends, the releasing lever has two upstanding trip arms 30, '30, these arms being arranged to contact with the lower edges of the dogs 24 and 25. In order to control the downward movement of this releasing lever 28, I provide the carriage 23, with the stop pin 4. The upward movement of this releasing lever 28, is stopped by the pin 6, shown in Fig. 6. Secured to the outer end of the carriage 23, is a bolt 34, shown in Fig. 6, which pivctally carries an'arm, 35, to the end of which ,is pivotally secured by means of a pin 37, shown in Fig. l, the apertured spacing bar 38.

As shown in the drawings, I secure to the upper edgeof the pallet 9, aflange 50, and secured centrally to this flange 50, is a U- shaped tearing yoke 46, which clasps upon the shaft 49. The yoke is secured by means of the. pin 48. vents any lateral displacement of the screw shaft 49, which at one end has a right handed thread and at the other end, a left handed thread, as shown in Fig. 4. One threaded end works within the pivotally held bearing block 45, while the opposite threaded end works within the pivotally held bearing block 45. cured to the shaft 49. By means of suitable pivots 55, these bearing blocks 45, and 45, are pivotally connected to the ends 53, of the clamps .54. These clamps in turn are l the rod D.

This bearing yoke 46, pre

An operating handle 59, is se-- pivotally secured to the pins 51 and 52, held within the flange 50, this construction being clearly shown in Fig.3. Inturningthe shaft 49, in one direction the" clamps 54,? are carried away from the pallet'while rotation in opposite direction carries the clamps against thepallet. to hold. the copy to the pallet, and in Fig. 1, a sheet :4, is shown as clamped to thepall'et 9.

By'means of the stopnut 18, the distance traveled by the spacing bar 38, may be accurately adjusted. The spacing. bar can further be accurately adjusted to the copy in simple raising up the-lever 28, which carries the dogs out ofengagement with the trip-rod, D. In order to raise and lower the carriage, it is simply necessary .to over These clamps are used come the friction of the spring 34, against the bar A. As soon as the -spacingbar has been properly adjusted the lever 28, is released when the dogs 24 and 25, again bite against the trip D." Then on depressing the spacing lever 41', the trip D, is carried down? ward and as the chisel edged dogs are in contact with the bar the entire carriage is carried downward. On releasing the tripe red I) the spring 21, promptly forces this rod upward, the rod 2escaping below'the chisel; edges of the dogs, which are moved upward, permitting the rod to escape. The downward movement of the dogs is of course controlled 1n their com ng 11]. contact with;

lated so that the spacingbar will accurately I feed down the copy, at. each stroke of the i operating lever 41. p 7

Copy holders embodying my invention: may be made in various sizes. The device is'simple. and inexpensive in construction both durable and efficientyin' operation and the copy can be instantly and accurately'secured to the pallet while the adjustment of the spacing bar is effected with ease,:accuracv and despatch.

Having thus described my said invention, what I claim as new and desire to secure by United States Letters Patent is:
